At least two of those who have fallen ill also visited Super Bowl Village together in downtown Indianapolis two days before the game.

From about 3-10 p.m., the individuals visited Rock Bottom Brewery, the Starbucks on Monument Circle, the Colts Pro Shop in Lucas Oil Stadium and The Huddle, as well as walking around the Super Bowl Village area.

Officials said both individuals had recently traveled overseas together and were not vaccinated.

More than 200,000 people visited the venue that day, but health officials said there have been no confirmed measles cases from that exposure.

Measles is a highly contagious respiratory disease caused by a virus that begins with a fever, cough, runny nose and red eyes seven to 10 days after exposure. The fever increases and a rash starts on the face and upper neck two to four days later, eventually spreading across the body.

Droplets from a sneeze or cough spray into the air and can remain active and contagious for up to two hours.

Health officials said measles is rare in the United States because of high levels of vaccination with the measles, mumps and rubella, or MMR, vaccine.

Children are routinely vaccinated for measles at 1 year old and again before entering kindergarten. Those born before 1957 are presumed to be immune to measles.

Measles poses a serious threat to unvaccinated infants, people with diseases affecting their immune systems and pregnant women.

Those experiencing the symptoms of measles are asked to stay home and consult a doctor.

Noblesville school officials said all staff members at Noblesville Intermediate School will have to show proof of immunization beginning Wednesday.

The Indiana State Department of Health has established a hotline to help answer questions from the general public. The hotline service will be available beginning Wednesday from 8:15 a.m. to 4:45 p.m. at 877-826-0011.
